After the banquet, Fang Er went directly to the side courtyard where Yuan Tiangang and Sun Simiao resided.
Sun Simiao was studying medical books, while Yuan Tiangang was tinkering with something among a pile of bottles and jars.
The two immortals were busy!
After standing in the courtyard for a long time and seeing neither of them looked up, Fang Er took the initiative to greet them.
"Uh, my young friend has arrived, please sit!"
Sun Simiao closed his medical book and gestured to a chair beside him.
"No need to sit, I've come to find Immortal Yuan for something."
"My young friend, you've come at just the right time!"
"Now, it's time to witness a miracle!"
Old Yuan finished speaking and poured some liquid into the beaker in front of him.
Then, he quickly retreated to the side.
"Holy cow! Young friend, get out of the way quickly!"
Sun Simiao heard this, quickly ran towards the house, and at the same time reminded Fang Er.
Fang Er glanced curiously into the beaker and saw a violent reaction occurring inside. He immediately understood.
He quickly followed Sun Simiao into the house.
The two immediately closed the door and crouched down, hiding below the window.
*Bang!* A sudden explosion from the courtyard proved their actions were correct.
After the explosion, they opened the door and saw Fang Er and Sun Simiao both laughing.
Old Yuan now looked like he had just returned from mining in Africa, his face was black, and his Taoist robe had several holes.
Especially on his shoulder, there was a shard of glass still stuck, looking truly miserable!
"Immortal Yuan? Are you alright?" Fang Er approached and poked Yuan Tiangang's arm with his hand.
*Pfft!*
Yuan Tiangang didn't answer immediately. Instead, he reached up and wiped his face, then pulled out the glass shard from his shoulder and said to Sun Simiao, who was coming out of the house, "Fellow Daoist Sun!"
Then, looking at Fang Er, he laughed, "Hahahaha, this little accident doesn't even count as a tickle, I'm used to it, I'm used to it!"
Fang Er: ...
What the heck, do I still want to say why I came?
Why does Old Yuan seem more and more unreliable?
Sun Simiao, however, was not surprised. He turned and went back into the house to get a medicine box. He skillfully stripped Yuan Tiangang's clothes and performed wound cleaning and suturing.
Fang Er: ...
Old Sun is so in sync! Yuan Tiangang just called out, and he knew what to do.
Old Yuan is truly a man! He didn't even groan when the needle and thread were sewn into his body.
After Sun Simiao cut the thread, Yuan Tiangang finally asked Fang Er about his purpose.
"My young friend just said he came to find me. Is there something?"
"My subordinate, Division Commander Yi, and Hua Niang are in love, so I wanted to ask Immortal Yuan to choose an auspicious date."
Fang Er deliberated for a moment and then suppressed the other matter.
This Old Yuan is too dangerous now.
Yuan Tiangang directly reached out and began to calculate.
"Half a month later, the second of February, extremely auspicious!"
Fang Er was stunned: "You don't even need birth dates?"
"Why would I need birth dates? We're all so familiar with each other, I can calculate it by your appearance." Yuan Tiangang replied matter-of-factly.
Fang Er felt speechless. Then why did he ask for my birth date back then?
"I can tell that this is not your true intention, my young friend."
After calculating the auspicious date, Yuan Tiangang suddenly looked at Fang Er with a meaningful expression.
Fang Er did have another matter, but he was scared by Yuan Tiangang's "miracle" just now!
This old fellow blew up a Taoist temple when he was in Fang Family Village, and he blew one up again after arriving in Shenyang!
He had practically transformed from a Taoist immortal cultivator into a terrorist.
As if sensing Fang Er's concerns, Sun Simiao interjected, "Young friend, don't worry, Daoist Yuan has a great life. He has at least thirty years of lifespan left, and he won't die from his recklessness."
So, within these thirty years, Yuan Tiangang possesses a constitution that prevents him from dying no matter how reckless he is?
This sounds so fantastical.
Fang Er looked at him disbelievingly: "Immortal Sun, are you sure?"
"Don't worry, with me here, there won't be any major trouble." Sun Simiao affirmed.
"Hahahaha, my young friend, quickly tell me, is there anything that requires me to witness a miracle?" Yuan Tiangang said with a smile, revealing his remaining two large yellow teeth.
"Alright! Since Immortal Sun has said so, I'll be direct!"
Fang Er decided to state his true intention.
He had come to Yuan Tiangang for rocket propellant columns.
With the current conditions, he could only create solid-fuel rockets, which required propellant columns.
This meant turning the gunpowder powder into a solid column, and furthermore, this cylindrical gunpowder column would need to have a groove carved inside.
This would have two benefits: first, the large burning surface area of the gunpowder would increase its burning speed.
Second, it would better utilize the recoil force generated by the gunpowder's combustion, maximizing the utilization of this power.
"Immortal Yuan, Immortal Sun, I won't hide it from you, these propellant columns are essential for us to understand the sky."
"I am currently making preparations. Once everything is ready, I can send people to an altitude of ten thousand meters to more directly comprehend the workings of the world and the cycles of the Heavenly Dao."
"What!"
"Are you serious, boy?"
Sun Simiao and Yuan Tiangang were instantly unable to contain their excitement. They grabbed Fang Er's shoulders from left and right.
"It's definitely true, when has this boy ever boasted?"
"It's just that the requirements for the propellant columns are too high, which is why I came to seek Immortal Yuan's help."
"What help or no help! I promise to do this for you, don't worry!"
Yuan Tiangang patted his chest and assured Fang Er.
The sphere that fell from the sky was not only Fang Er's concern; he also wanted to know what it was. Moreover, Fang Er's enticement with comprehending the workings of the world and the cycles of the Heavenly Dao was incredibly appealing to a cultivator!
After leaving the side courtyard where Yuan Tiangang lived, Fang Er returned home and spent half a day with Chai Yue.
The next day, he once again entered a state of seclusion.
However, as Chai Yue was in her late pregnancy, he deliberately set aside an hour each day to accompany her for a walk.
As the days passed, Chai Yue's body became increasingly cumbersome.
